If, for any reason, Yamaha decides to make a new keyboard that will not play styles from older Yamaha keyboards it would put me completely out of the market for that new keyboard. Some of us have spent a decade or more building gig sets and song styles we use for gigs and to start completely all over is a complete deal killer for me.

If they really do offer such a keyboard it will sure put business in Korg's and Ketron's pocket.
I doubt Yamaha is really that stupid.
